Definitions

  • FIG. 1S2 A first figure.
  • the present invention relates to a process for applying hot melt adhesives to corrugated kraft board in automatic corrugated paperboard machinery.
  • Hot melt adhesives in corrugated paperboard machinery to produced corrugated paperboard is a new development in the corrugated paperboard art.
  • the techniques and conditions previously employed with conventional starch based adhesives are not applicable to hot melt adhesives. This is the result of the intrinsic difference between hot melt adhesives and other types of adhesives.
  • Hot melt adhesives produce a bond by mere cooling as distinguished from cross-linking or other chemical reactions.
  • FIG. I a schematic representation for the production of a singlefacer corrugated paperboard is shown in FIG. I.
  • the corrugating medium 10 usually a mixture of semi-chemical paper and waste paper (kraft paper, newsprint, etc.) is treated with superheated steam and passed between the top corrugating roll 1, and the bottom corrugating roll 2.
  • the hot corrugated medium which is formed on the teeth 13 of bottom corrugating roll 2 is guided by finger 7 to follow said bottom corrugating roll to a point immediately prior to contact with transfer roll 4 which just touches the corrugated flutes 14 without any substantial pressure, so that the hot melt adhesive 15 is transferred to the tips of said corrugated flutes 14.
  • corrugated board flutes containing the hot melt adhesive are guided to follow bottom corrugating roll 2 by finger 7, which continues at a point immediately subsequent to the contact with transfer roll 4 to a point immediately prior to contact under pressure with liner 11, usually a suitable grade of kraft paper, between bottom corrngating roll 2 and pressure roll 3, thus pressing the adhesive bearing flute tips against the facer sheet to form single faced corrugated paperboard.
  • liner 11 usually a suitable grade of kraft paper
  • transfer roll 4 continually rotates at the same speed as the bottom corrugating roll 2, passing into the resin pan 8 which is maintained at the desired temperature by suitable heaters 9, for instance strip heaters.
  • the transfer roll picks up a thin film of hot melt adhesive 15, which is regulated to the desired thickness by use of the doctor roll 5 or the doctor blade 6.
  • the corrugating medium 10 is treated with superheated steam and runs between top corrugating roll 1 and bottom corrugating roll 2. This is a conventional step in the art, and the conditions that have been developed by the art to achieve the corrugating in the best manner result in the corrugated flutes 14 being at about 280 F. at the time they contact the transfer roll 4. It has been found that for proper transfer of the hot melt adhesive from the transfer roll to the tips of the corrugated flutes that the temperature of the transfer roll must be the same or greater than the temperature of the flutes, i.e., at least 280 F. Likewise, the temperature of the hot melt adhesive in the resin pan 8 must be the same or greater than the temperature of the transfer roll for proper pick-up of the hot melt adhesive.
  • the hot melt adhesive in the resin pan is usually in the range of about 300 F. to 350 F.
  • the hot melt adhesive on the transfer roll is usually in the range of about 290 F. to 310 F. but always the same or less than the temperature of the hot melt in the resin pan.
  • the difference in temperature between the resin immediately prior to transfer to the flute tips and the corrugated flutes is no greater than 30 F., regardless of the means of transfer.
  • Hot adhesive presently offer a number of advantages over conventional adhesives now in use.
  • the most outstanding advantages of hot melt adhesives over conventional adhesives of the prior art are 1) the improved efliciency of corrugating machinery and (2) superior characteristics of bonds formed with hot melt adhesives. Both of these advantages are attributable to the absence of water in the hot melt technique.
  • the speed at which the corrugtaing machinery can run is of course a measure of the units of work that a particular machine can produce during its up time.
  • Maximum operating speed with starch type conventional adhesives on corrugating machinery is about 700 feet of corrugated board per minute. Only single facer corrugated board, however, can be produced at this speed with the conventional water based adhesives.
  • double faced board such as that shown in FIG. 'III or double (FIG. IV) or triple (FIG. V) Wall paperboard is produced the speed which these machines can run is greatly reduced. The reason for this required reduction in speed is the water in the conventional adhesives.
  • the corrugating machinery can operates no faster than the water can be removed from the adhesive and paper. As there are additional layers of facer and corrugated medium, as
  • each layer of corrugated medium has a different phase, i.e. no pattern is developed as between the layers of corrugated medium.
  • corrugated board having random placement of the corrugated flutes in each layer in relation to the flutes of any other layer. This provides a corrugated paperboard of greater stability.
  • the double and triple wall corrugated board are being extensively used in packaging of large objects where maximum strength and protection is desired, such as furniture.
  • the corrugated medium although generally produced from semi-chemical paper and waste paper such as kraft or newprint, may be of other material such as kraft paper, thermoplastic and thermosetting materials and glass fiber.
  • semi-chemical paper and waste paper such as kraft or newprint
  • kraft paper thermoplastic and thermosetting materials and glass fiber.
  • steel foil One material on which recent developmental work has been done is steel foil.
  • FIG. VI is a schematic presentation for the production of single facer corrugated paperboard employing a metering device in place of a resin pan, transfer roll and doctor blade.
  • the enclosed resin pan 136 is connected to a metering device 137 by which the hot melt adhesive is applied directly from the resin pan to the corrugated flute tips 14.
  • the resin pan is maintained at the desired temperature by strip heaters 135.
  • the hot melt adhesive is forced out through the metering device 137 by application of constant pressure to the enclosed resin pan 136, for instance by the use of an inert gas, nitrogen, at a gage pressure suflicient to force the resin in the stated viscosity range, through the metering device 137 on to the tips of the corrugated flutes 14.
  • the adhesive bearing flutes are then contacted with the facer sheet 11 between the bottom corrugating roll 2 and the pressure roll 3 to form corrugated paperboard.
  • a metering device such as that represented in FIG. VI is used in place of a transfer roll, an added degree of flexibility is given to the corrugating machine.
  • a metering device may conveniently be placed in almost any relationship to point where the corrugated flute tips containing the adhesives are contacted with the facer. This allows the operator to obtain the maximum benefit from the particular properties of a given hot melt adhesive.
  • the hot melt adhesive bonds are unaffected by dampness or moisture.
  • the primary failure in the bond of wet corrugated board produced with hot melt adhesives is in the substrate (kraft paper in this case). If corrugated board produced from hot melts is soaked in water and allowed to dry, the bond is nearly as strong as it was originally, the fiber of the paper having been somewhat weakened; whereas corrugated board produced from conventional adhesives is no longer bonded after soaking because of the effect of water on the adhesive. Facer sheets treated with thermoplastic and thermosetting materials for strength and water resistance are more easily bonded with hot melt adhesives than conventional adhesive because of the nature of the hot melt adhesive bond.
  • the thickness of the adhesive layer applied is conveniently determined by the use of a doctor blade 6 or doctor roll 5.
  • the doctor blade is set at a particular clearance, for instance .010 inch. All of the adhesive above this thickness is scraped off and travels to the edge of the doctor blade where it falls back into the resin pan 8.
  • the doctor roll is set at approximately twice the clearance of the doctor blade in order to get the same amount of adhesive on the flutes because as the doctor roll rotates, it retains about onehalf of the adhesive passing through the clearance. It is of course desirable to employ as little adhesive as possible to obtain satisfactory corrugated board.
  • doctor blade clearances of .003 inch to .010 inch are employed to give hot melt adhesive thickness of about .001 to .005 inch applied on the corrugated flutes.
  • the suitability of a particular thermoplastic material as a hot melt adhesive depends on the proper viscosity at the operating temperatures to allow the adhesive to be deposited without objectionable stringiness to the corrugated flutes and to develop almost instantaneous hot tack, when the corrugated flutes are contacted with the facer sheets, suflicient to adhere the liner (liner and facer are interchangeable in the art) to the corrugated medium.
  • This viscosity allows for the penetra tion of the hot melt adhesive into the fiber of the corrugated medium sufliciently and to retain enough fluidity so that by the time the corrugated medium is contacted with the liner 11 between the bottom corrugating roll 2 and the pressure roll 3 that the adhesive will penetrate the fiber of the liner and encompass at least the first layer of paper fiber in order to form a tear seal fiber tear after the hot melt adhesive sets.
  • a tear seal is indicated when the adhesive bond produces failure in the substrate (in this case paper) when the corrugated medium and the facer sheet are pulled apart.
  • the viscosity range of 15,000 to 58,000 centipoises is required for any means of applying the hot melt to the corrugated flutes.
  • the viscosity of the hot melt adhesive In addition to the necessity for the viscosity of the hot melt adhesive to be such that it will wet the fiber of the facer sheet when the corrugated flutes containing the hot melt are contacted with the facer sheet at the pressure roll 3, the viscosity must be such that the corrugated paper is adhered to the facer sheet at the same time. This hot tack must be of suflicient strength to hold the two sheets together, i.e., an initial bond, until the hot melt adhesive has set.

  • the sample then consists of two layers of paper bonded together on internal surfaces over a two square inch area at one end. The test is made by gripping the free ends of the strips and pulling slowly in opposite directions perpendicular to the bond. A tear seal is indicated when the adhesive bond produces failure in the substrate (in this case kraft paper) at room temperature and at 25 F.
  • the second test is the delamination test. This test is made by forming a 2 inch lap joint with two 1 by 6 inch 50 pound kraft paper strips. The sample is joined by a two square inch area of adhesive having a thickness of 1 to 2 mils. The total length of the sample is 10 inches. The strip is suspended in a F. oven for one-half hour.
  • composition of a particular hot melt adhesive is of no consequence tothe present invention. Any hot melt adhesive which meets the ring and ball softening point and the viscosity requirements will operate according to the invention.
  • the amount of hot melt adhesive applied to corrugated flutes is not critical so long as a bond is formed, although generally corrugated board suitable for box manufacture has at least .75 pound of HMA per 1000 square feet.
  • the use of more than 1.25 pounds of HMA per 1000 square feet is not necessary for the production of satisfactory corrugated paperboard.
  • the use of more hot melt adhesive than this results in the excessive adhesive as shown in FIG. III by 105.
  • the buildup of excessive adhesives does add to the strength of the bond, however, such excessive built-up does not result in an increase in strength proportional to the excessive adhesive.
  • the corrugated board produced containing .75 to 1.25 pounds of hot melt adhesive has strength commensurate with commercial corrugated board produced from conventional water based adhesives.
  • FIGS. II and III represent single facer and double facer corrugated paperboard, respectively.
  • the facer sheet 101 is joined to the corrugated medium 103 at contacts formed between said facer sheet and the flutes 104 by the adhesive bond 102 produced when the hot melt adhesive sets.
  • All hot melt formulations that have desirable rates of developing tack that is, very slight cooling cause the viscosity to develop to the point where it will hold the corrugated sheet and the facer sheet together until the hot melt adhesive sets, do not have the necessary viscosities in the range of 15,000 to 58,000 centipoises at the operating temperature range. for corrugated paperboard machinery.
  • the rate of viscosity change is a constant property for a particular hot melt composition thus by adding plasticizers or fillers the viscosity at a particular temperature can be adjusted without aifecting the desirable rate at which hot tack develops.
  • Suitable plasticizers include the phthalates such as butyl benzyl phthalates, butyl cyclohexyl phthalate, phosphate esters, sulfonamides, chlorinated biphenyls and others known in the art. Fillers found suitable include asphalt, clays, such as bentonite clays, and asbestos.
  • Process according to claim 10 wherein the rate of contacting is about 500 feet per minute.
  • the temperature of said contacting is not greater than the temperature at which said hot melt adhesive is maintained prior to said contacting, the temperature of said flutes being about 280 F., the Brookfield viscosity of said hot melt adhesive being in the range of 15,000 to 58,000 centipoises in the temperature range of said contacting and a ring and ball softening point in the range of 160240 F., so as to transfer a portion of said hot melt adhesive onto said flutes and (c) subsequently contacting said flute tips bearing said hot melt adhesive with kraft paper liner so as to form a continuous sheet of corrugated paperboard.
